Harris Corp. Team Completes Internet Protocol Backbone For FAA Telecommunications Infrastructure Network

MELBOURNE, Florida, November 30, 2005 — Harris Corporation (NYSE:HRS) today announced that its Federal Aviation Administration (FAA) Telecommunications Infrastructure (FTI) program team has successfully completed the Internet Protocol over Asynchronous Transfer Mode (IP over ATM) backbone for the FTI network. Harris is the prime contractor and system architect for the FTI program, which was awarded in 2002. FTI will upgrade and improve telecommunications and operations functions at more than 5,000 FAA facilities nationwide, while significantly reducing operating costs.

“The completion of this portion of the project is a key milestone that will result in enhanced reliability and improved network performance,” said John O’Sullivan, FTI program vice president for Harris Corporation’s Government Communications Systems Division. “Eighty percent of the FAA’s operational IP traffic has been successfully migrated to the FTI network — a critical achievement since at least half of all future telecommunications requirements for the National Airspace System will require IP services. This milestone is a direct reflection of the strong cooperation, commitment and teamwork between the FAA and Harris.”

The IP over ATM backbone interconnects the nodes of the largest FAA facilities across the nation, consisting of 21 Air Route Traffic Control Centers and six other sites. It transports a variety of critical information including flight plans, surveillance data, weather data, and navigation aids. The backbone utilizes two different long-distance carrier networks, one from Sprint and one from AT&T, enabling the rapid distribution of significantly more information than was possible with the legacy FIRMNET network.

Harris FTI teammates include BellSouth Corporation, Qwest Communications International, Inc., SBC Communications, Inc., Sprint, Verizon Communications, and Raytheon Technical Services Company. The Harris FTI team is consolidating the Leased Interfacility NAS Communications System (LINCS), Data Multiplexing Network, Bandwidth Manager, and National Aviation Data Interchange Network into an integrated telecommunications infrastructure. Requirements include replacing more than 35,000 circuits, upgrading switching and routing services, improving network monitoring and control, implementing a state-of-the-art security system, and providing network-engineering services.
